This issue DOES occur on Flame 2.6
Result: Camera viewfinder displays a previous image in the view finder followed by a black screen for about a second.

-----------------------

This issue is somewhat different on Flame 2.5 and 2.2. 
Result: Instead of showing the previous image in the view finder, the screen will appear black initially and then refresh the viewfinder to the current view successfully. Since it isn't exactly the same issue, I am not sure if this could be a regression or not.

Not nominating as a blocker.  Can you take a look at this No-Jun?

[No-Jun Park [:njpark]]

I've seen this before, I think on Aries this is more prominent perhaps of the device optimization issue.  I agree that this is not a blocker yet.
